RF-Chord: Towards Deployable RFID Localization System for Logistic Networks
summary
Claims a deployable RFID locator that meets reliability, throughput and range by combining a digital 200 MHz wideband sniffer (using multisine carriers and LTE/5G transceivers) with a kernel-layer near-field framework and a multipath-suppression algorithm. It performs one-shot capture localization and localizes up to 180 tags 6 m away within 1 s, achieves 99th percentile 0.786 m, 0% miss and ~0.01% cross-reading in warehouse/fresh-food deployments, and sustains >100 tags/s in production — hardware and code are open-sourced.
